Publisher Summary This chapter discusses the formations of the Kinabatangan Group. Sapulut Formation is unconformably overlain by the Labang Formation, which is designated as beginning the Kinabatangan Group. Sedimentary conditions below and above the hiatus are generally the same, deep marine predominantly turbiditic, with shoaling carbonate areas. The formations and their lithology and age discussed are Labang Formation, Kulapis formation, Kalumpang formation, balung formation, and palaeogeography for end oligocene. Labang formation is widely separated localities, which are widely deposited and much eroded and is also overlain by the Tanjong Formation in apparent structural conformity. The Kulapis is a wholly marine redbed formation, readily mapped because both the sandstones and shales are red. They form many outcrops along the main Labuk road from Telupid to Sandakan. The Balung formation is gently dipping formation beneath the volcanic rocks of the Wullersdorf area near Tawau. The West Crocker, the Kulapis, Labang and Kalumpang formations are all of the same age.
